Hi Fraser, Why don’t we ever hear about any Mars missions landing near the polar areas where we know there is water ice? We are going to need these areas at some point, a looong long time from now, if we’re going to “colonize” that planet.
NASA sent the Mars Phoenix Lander to that region to dig into the regolith and see how much water ice was mixed in. They've also done pretty detailed scans from space and have mapped out the water down to the middle latitudes. https://www.kennedyspacecenter.com/blog/31/first-discovery-of-water-on-mars
